Hair disorders that involve hair loss are:
Androgenetic alopecia (pattern baldness), which is the most common and afflicts up to 80 percent of all men by age 70 and half of all women usually after menopause. Anagen effluvium, which is hair loss during the growing phase of the hair, can be caused by drugs or treatments, such as steroids or chemotherapy. Physical or psychological stress can cause telogen effluvium which is hair loss during the resting phase. Alopecia areata only occurs on the scalp or beard area with hair falling out in round, irregular patches. If you wear your hair too tight, you might get traction alopecia. Excessive hair growth includes two general disorders. The first is male pattern hair growth known as hirsutism, which is caused by an over abundance of male hormones. The other is hypertrichosis, which causes hair to grow anywhere on the body and can be congenital or acquired.
